As the G8 Summit kicked off today, all eyes were on British Prime Minister David Cameron to set the agenda. He announced that three Ts, taxes, transparency, and trade, would be priorities as world leaders settled in for the two day conference.

G8 is term for the Group of Eight, a group of the governments of eight of the world's eleven wealthiest countries. Those countries are:

The location of the summit rotates through the G8 countries and the leader of the host country sets the agenda. Last year, the summit was hosted by the United States and was held at Camp David. This year, the summit is hosted by the United Kingdom and opted to host the event in Northern Ireland.

Making sure we have more trade deals so we keep prices down, making sure we have greater transparency so we can help developing countries get the tax and revenue that they need, and this issue of taxation, making sure we crack down on tax evasion and aggressive tax avoidance, so right across the world, countries get the tax revenue they need to keep taxes down for hard-working people.

The recent spate of public tax charges are part of an overall message the G8 hopes to send to the world about the need for tax and economic transparency as part of efforts to shore up financial stability.

Jose Manuel Barroso, President of the EU Commission said, in reference to the problem, "I hope that bank secrecy and tax havens will soon belong to the past."

It's a lofty goal for the G8. Trillions of dollars are thought to be holed up in offshore accounts in tax havens around the globe resulting in hundreds of millions of dollars in lost tax revenue.

None of those tax havens - like Switzerland - will be specifically represented at the G8 Summit though some countries like Cyprus will be represented as part of the EU (European Union). The EU is considered the "9th member" of the G8 but is not allowed to host a summit.
